Question

Read the scenario.

A cell contains 90% water and 10% salt. The external solution contains 75% water and 25% salt.

Which statement is correct?

A>> The external solution is hypotonic, so the cell will shrink

B>> The external solution is hupotonic, so the cell will expand.

C>> the external solution is hypertonic, so the cell will expand.

D>> The external solution is hypertonic, so the cell will shrink.




I'm really thinking it's C... but I'm not one hundred percent

Answer 1

water flows from the area of low salinity to the area of high salinity, or from hypo to hyper.
C is right.

Answer 2

thank you so much!

Answer 3

Hypotonic is when a cell is having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. Hypertonic is when a cell is having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. HYPERtonic causes cells to shrink and HYPOtonic causes cells to expand.
